Attaching what are basically 3 of the “same” pics just because the glare and focus changes slightly.

In the second picture about what I guess would an inch to inch and a half below the IN USA, it looks like the remnants of a circular pattern. I had some success using metal polish to bring out details, then a piece of paper and lead pencil or crayon to lightly color over an area to see patterns.

^^You’re right, there does seem to be something there. Hard to be sure, but part of it might be an “8” or an “S” but I”m guessing “8”.
